Surface| Summary: | Coumarin-30 photocatalytic degradation processes on the surface of TiO2 and SiO2 were investigated at simultaneous action of ozone and UV radiation. It was observed that substrate sequentially accepts two protons to a molecule сoumarin-30 leading to formation of relatively strong intermediate compound. The greatest efficiency of destruction of сoumarin-30 was received at use of system UV/O3/TiO2. |
